## Answer

The idea behind `StandardScaler`

is that it will transform your data such that its distribution will have a mean value 0 and standard deviation of 1.

In case of multivariate data, this is done feature-wise (in other words independently for each column of the data).

Given the distribution of the data, each value in the dataset will have the mean value subtracted, and then divided by the standard deviation of the whole dataset (or feature in the multivariate case).
